It's a Living S02E09 - Young Love

Maggie invites the girls, Nancy, Sonny, and Dennis to a party at her house (Maggie calls it "a thing") as a gesture of thanks to all concerned for being nice to her as the new waitress at Above The Top, but the party (or "thing") is actually a rouse to get Dot to date Maggie's young college student brother Bobby, who is 22 years of age.  At the party, everyone there is bored silly (Cassie, in particular, who tells Jan that she's "bored out of my mind") and Maggie's plan to fix Dot up with Bobby back fires as he becomes attracted to Jan, who is in her early thirties.  Both Bobby and Jan have three dates with each other before Jan breaks up with Bobby because of her being concerned with the age difference between them.
